These are the reported stackvalidate warnings on tip/master with my Fedora-based config. There were 1399 warnings in 26 .c files and 16 .S files. It was mostly repeat warnings so I removed a lot of the repeats to keep it short. stackvalidate: arch/x86/crypto/aesni-intel_asm.o: aesni_set_key()+0x128: call without frame pointer save/setup
